Schedule parameters

This section describes the parameters that you can use to specify when to run a job.

You use a series of fields to specify the times for a job to run.

The numeric values you enter in the fields can be represented as follows:

Use an asterisk (*) to denote all valid values in the range. An asterisk can be followed by a forward slash (/) and a step value. For example, a value of */2 in the Hours field runs the job every 2 hours.
Note: Asterisk is interpreted specially in the Dates and Days fields. It matches its meaning in the UNIX/Linux cron facility. If one field has a literal value and the other has an asterisk, then only the frequency for the literal value is used. For example, if Month is *, Dates is *, and Days is 1, the execution occurs every Monday. See also the Day/Date examples below.
Use a range of numbers separated by a hyphen. For example, 8-11 in the Hours field specifies hours 8, 9, 10 and 11. You can follow a range by a forward slash (/) and a step value. For example, 0-23/2 in the Hours field runs the job every other hour.
Use a comma-separated list of a set of numbers (or ranges) separated by commas. For example, 1, 2, 3-5, 8.

The schedule is constructed from the values specified for the fields. Examples:


Values Desired schedule	Minutes	Hours	Dates	Months	Days
Run job daily, at 5 p.m.	0	17	*	*	*
Run job weekly, every Monday at 4:30 p.m.	30	16	*	*	1
Run job every half hour on every week day, skip weekends	*/30	*	*	*	1-5
Run job at 12:30 a.m., every other day	30	0	*/2	*	*

The Days and Dates fields use asterisks in a special way.

If one has an asterisk value but the other has a literal value, the job runs according to the field having a literal setting.
If both have non-asterisk values, then the job runs when either condition occurs.
If both have asterisk values, then the job runs every day.

Days/Dates examples:


Values Desired schedule	Minutes	Hours	Dates	Months	Days
Run job at 1:01 a.m. on the first day of each month. Dates uses a literal value; Days uses an asterisk.	1	1	1	*	*
Run job at 1:01 a.m. on every Monday in the month. Dates uses an asterisk; Days uses a literal value.	1	1	*	*	1
Run job at 1:01 a.m. on every Monday in the month and on the first day of the month regardless of whether that day is a Monday. Both Dates and Days use a literal value.	1	1	1	*	1
Run job at 1:01 a.m. every day. Both Dates and Days use an asterisk value.	1	1	*	*	*
